After Amazon came under fire for their financial practices in Europe, independent booksellers are leaving no doubt as to where they stand in the debate.

Signs reading “We Pay Our Taxes,” created by the Booksellers Association, have appeared in the windows of bookstores across the U.K.

During a hearing last week with the Public Accounts Committee, director of public policy for Amazon in Brussels Andrew Cecil was criticized for saying he’d have to get back to the committee with information on matters such as how the company was organized and its sales in individual European countries. Amazon channels its European sales through Luxembourg, where companies' profits are taxed at 11 percent, less than many other countries.

"It's just not acceptable," Margaret Hodge MP, the committee's chairman, said in an interview with Reuters about Cecil's failure to answer questions. "It's outrageous.”

Hodge told the BBC she thinks consumers should boycott Amazon and other companies – such as Starbucks – that were part of the hearing with the PAC. The British newspaper the Mirror is encouraging readers to avoid Amazon as well.

There are two different varieties of signs in booksellers’ windows – the first reads “Your Money, Your Bookshop, Your Community,” followed by “We Pay Our Taxes,” and the second states that the store “Can Pay Do Pay!,” with “We Pay Our Taxes” at the bottom.
